Homocysteine is a thiol aminoacid synthesized during the metabolism of methionine. Increased plasma levels of homocysteine can be the result of mutations in the enzymes responsible for homocysteine metabolism, particularly cystathionine-β synthase (CBS) and 5,10-methylenetetrahydrofolate reductase (MTHFR). Additionally, nutritional deficiencies in B vitamin cofactors required for homocysteine m Read More

Recently interest has been focused on the administration of allergen specific immunotherapy by the oral route particularly sublingually. The mechanism by which sublingual immunotherapy exerts its effects remain unclear. Most likely, allergen captured within the oral mucosa by Langerhan's-like dendritic cells play a role in subsequent T cell responses. There is a growing body of evidence to support the role of reg Read More

Annexins are characterized by the ability to bind phospholipids of membranes in the presence of Ca2+. Annexin A5 represents a typical member of this protein family and is a natural occurring highly specific ligand for phosphatidylserine (PS). The exposure of PS is one major “eat me” signal for phagocytes of apoptotic and necrotic cells. Apoptotic cells are normally cleared via an anti-inflammatory pathway. In contrast, the uptak Read More

Cardiovascular diseases as hypertension, angina and/or supraventricular arrhythmias are among the most important death causes in the world. For the treatment of heart pathologies, calcium channel entry blockers are very important drugs, owing to their therapeutic versatility. Although few calcium antagonists described until today are structurally related to diltiazem and to the benzothiazepine class, the still high pharmaceut Read More

Malaria is the most important parasitic disease worldwide, affecting more than 500 million people and causing close to 1 million deaths per annum. This serious fact is mainly attributable to the emergence of drug resistant strains of Plasmodium falciparum. The advances made in malaria chemotherapy based on unique aspects of the biochemistry and physiology of the responsible agents for this disease, parasites of Plas Read More

This review critically surveys the literature published mainly within this millennium on the new and emerging applications of silybin (pure, chemically defined substance) and silymarin (flavonoid complex from Silybum marianum - milk thistle seeds). These compounds used so far mostly as hepatoprotectants were shown to have other interesting activities, e.g. anticancer and canceroprotective and also hypocholesterolemic Read More

Loads of reactive oxygen species (ROS), including superoxide anion and nitric oxide, that overburden antioxidant systems induce oxidative stress in the body. Major cellular targets of ROS are membrane lipids, proteins, nucleic acids, and carbohydrates. Circumstantial evidence suggests that ROS play a crucial role in the initiation and progression of various diseases in children and adolescents. The involvement of ROS and oxidativ Read More

Premature ovarian failure (POF) is defined as the cessation of ovarian function under the age of 40 years and is characterized by amenorrhea, hypoestrogenism, and elevated serum gonadotropin concentrations. POF affects 1% of all women and occurs in approximately 0.1% before the age of 30 years. To date, mutations associated with POF have been identified in a small number of genes, including those encoding inhibinα ( Read More

Psoriatic arthritis (PsA), an inflammatory joint disease associated with psoriasis of the skin, has a heterogeneous pattern expressed by different manifestations, such as mild mono-oligoarthritis, a very severe, erosive and destructive polyarthritis indistinguishable from rheumatoid arthritis, and spondylarthropathy with axial involvement or enthesitis. The disease pattern often differs between patients as well as within the sa Read More

The NF-κB/Rel signaling system is a paradigm for gene activation in response to inflammatory and menacing stimuli. Given the growing body of evidence showing an important involvement of NF-κB for the onset of autoimmune diseases and different types of cancer, NF-κB is an important drug target for the adjuvant therapy of these diseases. Great efforts have been made for the development of highly specific NF-κB inhibi Read More
